IMPROVEMENT IN MACHINES FO R DRESSING SHINGLES.

Specification forming part of Letters PatentNo. 158,946, dated January 19,1875; application filed January 4, 1875.

To all whom it may concern:

Be it known that I, SAMUEL M. KING, of the city and county of Lancaster, and State of Pennsylvania, have invented a new and Improved Machine for Dressing Shingles; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming a part of this specification, in which- Figure 1 is a top view. Fig. 2 is a vertical longitudinal section. Fig. 3 is a vertical crosssection in line at m of Fig. 2.

The invention relates to and consists in novel means whereby both sides of a shingle may be planed and face-smoothed at a single operation, as hereinafter more fully described, and subsequently pointed out in the claim.

A represents a frame, having, upon one end, uprights or, upon which are held the revolving shafts B G, provided with spur-wheel b and pinion 0, While upon the other uprights, a are supported the cross-pieces a and longitudinal pieces (9. Between the horizontal pieces a a, and to the inside of each, is attached an inclined track, D. At the upper end and across these tracks D D is located the rest E, against which is sustained the small end of the shingle, While the large end is held beneath a spring-clamp, F. G is the bottom planer, provided with a cutter, g,- and H, the upper planer, having cutter h, the two placed opposite to each other, and connected by the studs g g, that pass loosely through holes h As the planers G H are drawn forward over I the shingle from butt to point, the subjacent planer G gradually rises on the inclined tracks D D, and accommodates itself to the bevel of the shingle, and forces the shingle at the same time to gradually rise in a corresponding manner in front of the upper planer, H.

By this machine not only may the shingle be face-smoothed uniformly and in a workmanlike manner, but this may be done with such rapidity as nearly to lessen one-half the usual cost of this mechanical operation.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

' The combination, with rest E, clamp F, up-
